DZDLP electric low-temperature single seat regulating valve

Product IntroductionDZDLP electric low-temperature single seat regulating valveIt is a pressure balanced regulating valve designed specifically for low-temperature environments, consisting of an electric actuator and a straight through single seat valve body, supporting medium flow control under low-temperature conditions.

Product Features:

1. This series of valves consists of a valve body, a valve seat, a valve disc pressure sleeve, and a valve cover, matched with an electric actuator;

2. The valve seat and valve disc are designed in different structural forms to meet different throttling fractions and two adjustment forms with linear and equal percentage flow characteristics;

3. The valve body structure is arranged in a Z-shape, with multi-stage throttling, high adjustment accuracy, and strong universality. It can be used for regulating the flow rate of cooling water under various pressure differentials and flow capacities.

4. The throttle parts of each stage of the valve seat and disc are made into a reasonable line shape, which can prevent cavitation and noise, and can smoothly adjust the flow rate; 5. The sealing gasket between the valve seats is made of flexible graphite, which has good compressibility and basically no leakage when the valve is closed, with good sealing performance;

working principle

Electric control valve is one of the important links in the automatic control system of the production process. It uses AC220V power supply voltage as the operating force, receives a unified standard signal of 0-10mA DC or 4-20mADC, converts it into an up and down displacement corresponding to the input signal, automatically operates the valve, changes the opening displacement of the valve, and thus achieves automatic adjustment and control of parameters such as pressure, flow rate, temperature, liquid level, etc. of the process pipeline fluid medium. Electric control valves are widely used in the automation and remote control of industrial production processes such as chemical, petroleum, metallurgical, power station, textile, papermaking, and pharmaceutical industries.
